Investigation Of Breeding Objectives And Indexes-In-Retrospect, Hunter F. Valasek Dec 2023

Investigation Of Breeding Objectives And Indexes-In-Retrospect, Hunter F. Valasek

Department of Animal Science: Dissertations, Theses, and Student Research

This thesis presents two projects that investigate the impacts of breeding objectives and indexes-in-retrospect within the beef cattle industry. The first project synthesized how changes due to planning horizon, breeding system, and sale endpoint in the economic breeding goal of cattle influence the relative emphasis of traits as well as the re-ranking of selection candidates. A total of three breeding systems that represent straightbred and crossbred cattle were used along with six planning horizons (2, 5, 10, 20, 30, and 50 yrs.) for both a weaning and slaughter point of sale. The combination of these different breeding objective attributes resulted …


Mosaic Agriculture: A Guide To Irrigated Crop And Forage Production In Northern Wa, Geoff A. Moore Mr, Clinton K. Revell Dr, Christopher Schelfhout Dr, Christopher Ham Mr, Samuel Crouch Mr Mar 2021

Mosaic Agriculture: A Guide To Irrigated Crop And Forage Production In Northern Wa, Geoff A. Moore Mr, Clinton K. Revell Dr, Christopher Schelfhout Dr, Christopher Ham Mr, Samuel Crouch Mr

Bulletins 4000 -

The Bulletin is a comprehensive guide for pastoralists, agronomists, agribusiness and the broader community on the growing of irrigated crops and pastures within a rangeland pastoral setting.

Dispersed irrigation developments on stations throughout the northern rangelands (sometimes referred to as mosaic agriculture) has created opportunities for the introduction of more productive forage species and pastoralists can now grow high quality forage for 12 months of the year. This can help to overcome the key constraint of traditional pastoral systems, the low quality of the feed over the dry season that typically results in stock losing condition.


Exploring How Maternal Phosphorus Status Affects Calf Growth And Performance, Elizabeth Lafferty, Beth Kegley, Brittni Littlejohn, Jeremy Powell Jan 2021

Exploring How Maternal Phosphorus Status Affects Calf Growth And Performance, Elizabeth Lafferty, Beth Kegley, Brittni Littlejohn, Jeremy Powell

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Phosphorus is an important component of bodily functions and is critical for adequate growth and development. This experiment evaluated the effect of maternal phosphorus intake on the growth and health of the calves. Treatments were 1) a free-choice mineral containing no supplemental P or 2) a free-choice mineral with 4% supplemental phosphorus. Primiparous, or pregnant for the first time, crossbred Angus beef cows (n = 36) were stratified by body weight and pregnancy status (bred by artificial insemination or natural service) then assigned to pasture groups (4 groups, 2/treatment, 9 heifers/group). These bred heifers had been receiving these same dietary …


Optimal Calving Time For Beef Cows In Southwest Missouri, Briana Rose Verploeg May 2020

Optimal Calving Time For Beef Cows In Southwest Missouri, Briana Rose Verploeg

MSU Graduate Theses

The purpose of this study is to determine if a optimal time of year exists for beef producers to have cows give birth in southwest Missouri for maximal net returns from calf sales and increased cow reproductive performance. To make this determination, data were collected which included year-round forage nutritive value, calf pre-weaning growth, cow energy efficiency and reproductive performance, and income and cost values. Cow and calf field data were gathered for the 2014-2018 production years at Missouri State University’s Leo Journagan Ranch. Monthly forage samples were collected from study cow pastures from 2016 through 2018. Calf, cull cow, …


Alternative Feeding Strategies For Growing Cattle Grazing Endophyte-Infected Tall Fescue During The Summer, Kerri A. Johnson May 2018

Alternative Feeding Strategies For Growing Cattle Grazing Endophyte-Infected Tall Fescue During The Summer, Kerri A. Johnson

MSU Graduate Theses

Two experiments were conducted to determine animal performance of alternative feeding strategies to heifers grazing endophyte-infected tall fescue during summer months. In Experiment 1, 40 Limousin heifers (261± 40kg initial BW) were stratified by weight and assigned to either a spring harvested tall fescue silage diet or grazing endophyte-infected tall fescue pasture with grain supplement having either natural or artificial shade for 80 days. In Experiment 2, 40 Limousin heifers (277 ± 44kg initial BW) were stratified by weight and assigned to either a traditional grain supplement or feather-meal supplement (rumen bypass arginine supplement) with natural or artificial shade while …


Succession Planning And Perceived Obstacles And Attractions For Future Generations Entering Beef Cattle Production, Lee L. Schulz, Georgeanne M. Artz, Patrick J. Gunn Apr 2017

Succession Planning And Perceived Obstacles And Attractions For Future Generations Entering Beef Cattle Production, Lee L. Schulz, Georgeanne M. Artz, Patrick J. Gunn

Journal of Applied Farm Economics

This study provides valuable insights into cow-calf producer and feedlot operator succession plans for transferring cattle operations upon exiting the industry. Across both cow-calf producers and feedlot operators, about 50% expect to be raising cattle for 10 more years or less; however, about 39% of these producers do not have a succession plan in place. Cow-calf producers view a rural lifestyle, self-employment, working with livestock, and working with family as the biggest attractions to future generations entering beef cattle production. Cow-calf producers view environmental regulations, land tax policy, and expansion of corn and soybean acres as the biggest obstacles. Feedlot …

Beef Producer Perferences For Various Livestock Revenue Protection Products: A Conjoint Approach, Deacue Fields Iii

LSU Doctoral Dissertations

The federal government has recently approved legislation to develop revenue insurance products that are affordable and user-friendly for livestock producers. The features of the products will be the ultimate determinant of product acceptance among producers. The objective of the study was to determine the relative importance of livestock revenue insurance product attributes as well as to identify the characteristics of beef cattle producers who prefer certain levels of a given product attribute. Conjoint analysis was utilized to determine the importance of selected attributes. Conjoint Designer was used to develop eleven hypothetical insurance products from four attributes with three levels each. …

Pilbara Steer Growth Evaluation : 1994 - 1996, Wayne Fletcher, Brian Mcintyre, Shane Cridland Dr, J L. James Jan 1996

Pilbara Steer Growth Evaluation : 1994 - 1996, Wayne Fletcher, Brian Mcintyre, Shane Cridland Dr, J L. James

Agriculture reports

Growth potential of steers in the Pilbara - a summary. The trial was conducted over a range of conditions on three locations. The pasture type at Wyloo, the Ashburton River frontage, which is regarded as one of the most productive pasture types in the area, combined with conservative stocking, a fresh paddock and excellent seasonal conditions during 1995, gives us an indication of the District's potential. In extrapolating any of these data to other cases, consideration must be given to adjustment base


Finishing Kimberley Cattle In The South-West, Brian L. Mcintyre, Bill Ryan, Neville Macintyre Jan 1989

Finishing Kimberley Cattle In The South-West, Brian L. Mcintyre, Bill Ryan, Neville Macintyre

Journal of the Department of Agriculture, Western Australia, Series 4

The idea of integrating the Kimberley cattle industry with that in the south-west of Western Australia is no new, but until recently it had not been critically evaluated.

Over the past eight years the Department of Agriculture's Beef Cattle Branch has been assessing the performance of Kimberley cattle transported south for finishing in the agricultural areas.

This research has show that Kimberley weaners can be finished in the south, and that under the present (December 1988) economic conditions it is more profitable than running breeding cattle in the south-west and comparable with fattening store steers.


Prospects For Leucaena On The Ord, D Pratchett, Tim Triglone Jan 1989

Prospects For Leucaena On The Ord, D Pratchett, Tim Triglone

Journal of the Department of Agriculture, Western Australia, Series 4

For the past few years, the Department of Agriculture has been fattening cattle on the forage shrub leucaena which is grown under irrigation with pangola grass. About 400ha of leucaena is under commercial production in the Kimberley.

Cattle grazing leucaena show promising growth rates but other problems need to be overcome before its use is more widely adopted. Leucaena establishes slowly. It is also costly to transport fattened cattle to southern abbatoirs.


The Problems And Prospects Of The Kimberley Pastoral Industry, R B. Hacker Dec 1982

The Problems And Prospects Of The Kimberley Pastoral Industry, R B. Hacker

Resource management technical reports

The pastoral industry in the Kimberley region began in the early 1880s withthe introduction of cattle overlanded from Queensland and New South Wales into the East Kimberley and with the almost simultaneous introduction, by sea, ofboth sheep and cattle into the Fitzroy Valley.Occupation of the more accessible areas was gradually achieved by theprogressive extension of these two arms of settlement which ultimately metaround the present location of Fitzroy Crossing. Extensive development of themore rugged areas of the North Kimberley came later with the construction ofreasonable access roads to the few isolated stations which had been initiallyestablished in this area.


A Forecasting-Programming Method For Placement-Sales Decisions For A Beef Feedlot, Franz Schwarz, J. B. Hassler Apr 1979

A Forecasting-Programming Method For Placement-Sales Decisions For A Beef Feedlot, Franz Schwarz, J. B. Hassler

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

This bulletin reports on a practical multi-period linear programming procedure as a management tool for decisions on placements and marketings for a beef feedlot operating over time under market uncertainty. Although the conclusions were based on application to an individual firm with uniqueness in time and space, the model should be equally appropriate for any firm's production and marketing decisions through time.


Beef Marketing As A Guide To Production Techniques, D J. Barker Jan 1974

Beef Marketing As A Guide To Production Techniques, D J. Barker

Journal of the Department of Agriculture, Western Australia, Series 4

Until about a year ago beef was in strong demand. Almost anything was marketable at favourable prices and good profits could be made even if the production process was wasteful in some respects.

Now the tide has turned. The demand for beef is weak, prices are low and some types of beef are virtually unsaleable. Now more than ever it is important to look critically at the factors which affect beef quality and to seek ways of reducing waste in both feed used and end products marketed.

This article examines production and marketing of beef and points out some inadequacies …


Grain Finishing Of Beef Cattle Grazing Dry Pasture Or Stubble, D J. Barker Jan 1971

Grain Finishing Of Beef Cattle Grazing Dry Pasture Or Stubble, D J. Barker

Journal of the Department of Agriculture, Western Australia, Series 4

WHEAT quotas, poor wool prices and the availability of cheap grain on the farm have stimulated interest in grain finishing of cattle for out-of-season beef production. For many years, Animals turned off in the autumn-winter period have brought better prices than those sold in summer, at the end of the pasture flush.

Feeding grain supplements to cattle on dry pasture or stubble requires less capital than feedlotting and saves the cost of handling and processing roughage.

This article gives the essentials for grain supplementation of dry pasture or stubble but warns that grain finishing is unlikely to be profitable outside …


Feedlots For Beef In W.A. : Some Guiding Principles, D J. Barker Jan 1971

Feedlots For Beef In W.A. : Some Guiding Principles, D J. Barker

Journal of the Department of Agriculture, Western Australia, Series 4

FEEDLOTS are small enclosures where all of the animal's feed is supplied from an outside source. Compared with grazing, feedlotting is an expensive method of beef production.

This article gives a guide to the requirements for establishment and management of a farm feedlot, especially the basic equipment and materials, the type of cattle most suited to feedlotting, rations and feeding techniques.

The author warns that skill and experience are needed to run a feedlot and describes feedlotting as an expensive method of beef raising when compared with grazing.

When Is A Cattle Feedlot Profitable?, J T. Stoate Jan 1971

When Is A Cattle Feedlot Profitable?, J T. Stoate

Journal of the Department of Agriculture, Western Australia, Series 4

THE current surge of interest in feedlots stems from low coarse grain prices and comparatively low early summer baby beef prices. Cattle raisers sense the opportunity for higher prices by holding the cattle on the farm over summer and autumn, and grain producers see better returns from barley and oats fed to cattle than sold as grain.

This article examines the profitability of cattle feedlots and presents sample budgets for two typical situations—the farmer who produces his own cattle but buys grain, and the cereal grower who produces grain but buys in cattle for finishing in a feedlot.

A ready …

Promising Results On West Kimberley Pindan Country, A L. Payne Jan 1969

Promising Results On West Kimberley Pindan Country, A L. Payne

Journal of the Department of Agriculture, Western Australia, Series 4

IN the 22 to 28 inch rainfall belt of the West Kimberley area of Western Australia are extensive areas of what is locally known as "pindan" country.

The term "pindan" refers to a light red or yellow sandy soil type supporting scattered Eucalypts, sparse-dense wattle scrub and grasses such as curly spinifex, ribbon grass and native sorghum.


Winter Beef Production Trial : Wongan Hills Research Station, D J. Barker, H. G. Cariss Jan 1968

Winter Beef Production Trial : Wongan Hills Research Station, D J. Barker, H. G. Cariss

Journal of the Department of Agriculture, Western Australia, Series 4

IN 14-inch rainfall districts most rainfall occurs between May and October. It is d i f f i cult to keep beef animals fattening on summer dry pastures but such areas do have a ready supply of locally grown cereals.

Using these materials as the basis of a supplement it is possible to market prime baby-beef by June-July.

The higher prices obtained for this "winter" beef more than offset the cost of supplementary feed.
